Green groups press Interior and EPA on methane emissions

More than 90 green groups across the U.S. are calling on the Environmental Protection Agency and Interior Department to regulate methane emissions from oil and gas industry operations.

"EPA needs to take immediate steps to produce regulations to directly reduce methane pollution from new and existing equipment from this industry," the groups wrote in a letter to Interior Secretary Sally JewellSarah (Sally) Margaret JewellOvernight Energy: Zinke extends mining ban near Yellowstone | UN report offers dire climate warning | Trump expected to lift ethanol restrictions Zinke extends mining ban near Yellowstone Blind focus on ‘energy dominance’ may cripple Endangered Species Act MORE and EPA chief Gina McCarthyRegina (Gina) McCarthyOvernight Energy: Ethics panel clears Grijalva over settlement with staffer | DC aims to run on 100 percent clean energy by 2032 | Judges skeptical of challenge to Obama smog rule Judges skeptical of case against Obama smog rule California commits to 100 percent renewable energy by 2045 MORE on Thursday.

The groups include the Clean Air Task Force, Center for Biological Diversity, and National Wildlife Federation.

They go on to say that without firm controls on methane, the nation will not reach the targets laid out by the Obama administration to slash greenhouse gas emissions by 2020.

The Interior Department must also revise its rules on air pollution from offshore oil and gas sources to accommodate a "fragile" Arctic environment, the letter adds.
